I agree that slimepunk doors could be much better (easier to reach button, a bit faster, +invisible brushes so people can't get stuck on them, and delay for buttons), but they are certainly not map breaking. Maybe you should learn the vent system, as pretty much every area is accessible from there for up to mara (+mara if u evolve before coming out, as it doesn't fit back in easily enough to be worth trying).
Procyon IS NOT enormous. Eggspam was never a problem even in 1.1 on a high bp server, with no bp queue. It can't possibly be now. Again, go learn the map.
Pulse does have 1 place where you could get outside the map that can be fixed like the tremor one, but another that can't... I agree with bad gameplay, tho only if human team sux at start, as better alien team can easily stop them from building RC.
